fmajor,
The 7MM Rem Mag was designed to be a long range elk rifle. It will kill the biggest elk on Earth. But so will a lot of other cartridges.
Hunter tend to focus on cartridges, and give short shrift to what really matters: putting bullets where they need to go. A .30-30 Win will kill elk just as dead as any mega magnum if a hunter puts his bullet where it needs to go.
In ALL matters of that which is living, biological science is controlling, not cartridges. Put any bullet through any animal's blood pumping apparatus, and it will die. Nothing living remains in that condition without oxygenated blood to its brain, not even elk.
So far, I haven't been drawn for anything. I might just spend hunting season in Central America hunting huge tuna. If I were drawn, I'd go with a .270 Win. The last elk I killed was with my 7MM Rem Mag. But carrying heavy guns up and down high ridges of the Rockies gets old after about 10 minutes. I'd much rather carry a light rifle. However, the 7MM Rem Mag is a elk cartridge extraordinaire. Dead is dead, and the 7MM Rem Mag will assuredly reduce any elk to that condition/
I'm good with any cartridge a hunter wants to carry. After all, he's doing the hunting. He ought to know what's right for him. However, he'll get me looking askance at him when he tries to tell me that his .338 Rem Ultra Mag will kill deader than a .308 Win. It won't, provided bullets from either destroy topside blood pumping equipment. Animals live but seconds when their brains are denied oxygenated blood.
BTW, just some helpful advice: go with Partitions.
